Qiniu Seven cow problem solution
Many people will use the seven bull video transcoding problem, to the video transcoding to apply to a variety of terminal video, but also some users of transcoding service code rate, frame rate, resolution and so on do not understand much. I don't know how to set these parameters. Let me give you a little bit of science.
Problem Resolution 1, we provide various transcoding practical parameters in the seven bull background. You can look at the following:
If you want to see the contents of the various processing styles in the above image can be selected, there will be a parameter setting string below.
2, the user has a misunderstanding, is that he does not know the code rate, and frame rate parameters such as the setting, in fact, you use seven bull transcoding time, turn into a class of video format, is the default rate and other information. No specific go-to settings. If you do not want to set it, you can change the parameters yourself. 3, users of high-definition in Ching correlation code rate, frame rate error.
Many people think that high-definition video with the code rate, in fact, HD video and Ching video only with the resolution, so only need to change the resolution parameters of the transcoding to achieve high-definition and Ching video transcoding.

Switch to the phone-side parameters (just for example, does not represent all models 320*240)

Also can this (this will take the original video bitrate and other parameters as the default transcoding parameters, the following operation only modified the resolution, for some users do not understand the code rate and frame rate, it is recommended to try this setup mode)
